To all whom it may concern:

- Be it known that I, FRANK/A. Pl upmrri, a citizen of the United States, resldlng in Pottstown, Montgomery county, State of Pennsylvania, have invented certain Improvements in Coolers, of which the follow- .the temperature of' drinking water, beer and the like the construction being such as to cause the rapidwcooling of the liquid passing through the device as well as a steady flow thereof at the outlet of the device." 1 I f It is further desired to providean efficient form of cooler with novel means forfreduc- .ing to' a minimum the foaming of the liquid operated on';the arrangement, of parts being such asto facilitate the inspection and cleaning of the devicefas Well as its inexpensive and economical construction.

I These objects and other advantageous ends I secure as hereinafter set' forth,',ref-

erence being had to, the accompanying drawings,; in which, Y Figure 1 is a central vertical section of a cooler constructed according to my invention; y H Fig. 2isa plan and Q F ig. 3 is horizontal section taken through the pivots of the clamping bolts and through the, outlet opening.

In the above drawings 1 represents an elongated cylinder of relatively thin metal,

which together with the other metal parts of the apparatus coming in contact with the liquid to be cooled is preferably made of German silver. To one end of the casing 1 is sweated a base casting 2 while a collar 3 is likewise sweated to its opposite end. This collar has projecting from it, three or any suitable number of properly spaced lugs 4 to each of which is pivoted a. clamping bolt 5 and these bolts are designed to extend between the branches. of forked lugs 6 on a clamping plate 7 fitting over and holding against the upper end of the cylinder 1, there being wing nuts 10 operative on the bolts and engaging'this plate to retain it in its clamping position. Between the plate 7 and. the top end of the casing 1 is confined a cover 9 which has an annular packing containing recess fitting over said end and making a liquid tight joint therewith when the V Specification of Letters Patent.

wing nuts are set up. The cover 9 has a central boss into which is screwed a threaded bushing 11 screwed .or otherwise connected to. a spherical shell 12 serving asan air chamber.

Within thecasingor'shell- 1 is mounted a casting 13 preferably of porcelain constituting a bafile element having a central cylindrical portion, 1 1 of such a diameter asto provide anelongated annular space or chamber between its surface and the inner walls of the shell or casing :1. At its lowerend said casting has helical ribs v.15 similar to the threads of a screw which extend to within a short distancei'of its lower extremity and on the opposite end of the element 13 is a second helical rib 16 which with the rib 15, isof such dimensions as to-closely fit the bore of the shell land efiectual'ly. prevent leakage of appreciable quantities of liquid between the outer edge of any rib and the casing wall. .1

The base casting 2 is provided with a projecting boss 17 in which is threaded abushing 18 whose inner end projects into "the channel formed between the lowermost portion' of. the rib 15 and the. casingl, it being noted that this bushing like'a second bushing 21 threaded into a boss 20 of the collar 3, has the inner end of its passage curved so as to discharge'or receive liquid in a line practically, at right angles to its center? line.

Moreover the walls of the passages of-both of these bushings is formed in a gentle rather than in an abrupt curve so that fluid passing therethrough has its direction of motion gradually changed. The bushing 21 in the boss 20 opens into the space defined by the upper end of the rib 16, the'cover 9 and, the wall of the casing 1, the top of the bafiie element 13 having a projecting boss 22 engaged.

by said cover and transversely slotted or otherwise recessed at 23 to permit of the free flow of air between the casing and the interior of the air chamber 12.

Under conditions of use liquid entering the bushing 18 has its direction of flow changed thereby so that it passes into the tortuous channel provided by the rib 15 without being permitted to form eddies orbeing so disturbed asto foam objectionably,

it being understood that the cooler as a whole is pla ed within a suitable container and surrounded by ice or other cooling meium.

nrpasan ihroagh mechanism g eaned by the rib 15 the liquid is forced to travel in intimate "conta-t With'a considerable portion of the inner surface of the casing 1' and thereafter enters the relatively large annular chamber or container formed between the central or unribbed portion 14 of the baiile element 13 'an'd'the wall of the casing. Obviously a considerable: volumeof liquid "collects in this chamber and lies in contact with a 'furt he'r'zexpanse of the ilmer surfac'e of the casing, from whi'c h itip'ass'es into the -'tor muons/channel formed by the :rib I6 and thence into the. bushing 21 Where its direction of movement is changed so' tha t it ulti mately' flowsxout of the. casing 1 in radial directionw'" lithe space between. the upper end ofthe main portion 'of'the'baffle element and the cover 9 contains. air or gas as does also the spherical chamber 1 2, with the f-re'sult that 'i anywari ations. in the rate at which" liquid flows to or a is dl'aWii "from the co ol-erv are 'Iriinimi'zed by the "action ott siroh gas which i's'compressedoi permitted to expand by the changes of pressure of the-flowing liquid due "to the above'not'ed Variations in 'it'sr flovr. y
